m im?! f0;- wiwe'ls havnew link; 2; approx? tia-as lugs 52 ii 332 {he conform ing to and placed in contact with the adjacent surfaces of said tires, lugs connected to each of the said bars and extending centrally therefrom on both sides longitudinally of the chain, and links the ends of which are placed between and pivotally connected to the said lugs, the thickness of the last aforesaid links being greater than the distance between the said tires at the bases thereof.

2. A non-skid device for double tired Wheels comprising a series of frogs provided with perforated ears at each end, hinged togcther by a series of bar links having perforated ends, one link being placed between every two frogs and pivoted thereto by closely fitting pins passing through the pcrforated ends of the links and the perforated ears of the frogs, whereby an endless band is formed encirclin the wheel, flexible only in the plane thereof, and seated in the groove between the tires.

3. A. non-skid device for. double tired wheels comprising a series of frogs hinged together to form an endless band encircling the wheel, flexible only in the plane of the wheel and seated in the groove between the tires, the laterally extending arms of said frogs extending across the treads of the tires and beyond the cemer lines thereof.

4. An anti-skidding chain for Wheels having twin-tires, comprising a series of bars each extending transversely approximately to the centers of said tires, the inner face of each bar including curved portions conforming to and contacting with the surfaces of said tires, and the outer face presenting a substantially straight transversely extending cleat or ridge narrower than said inner face, and the side faces presenting lugs extending peripherally of the Wheel and between the two tires thereof, and links secured to said lugs and connecting said bars together in series.

In testimony that I claim the foregoing my invention, I have signed my name in presence of two subscribing witnesses.
